  2. Carbon dioxide (data page) - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_(data_page)

    Table data obtained from CRC Handbook of Chemistry and Physics 44th ed. Annotation "(s)" indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid. For kPa values, where datum is whole numbers of atmospheres exact kPa values are given, elsewhere 2 significant figures derived from mm Hg data.

  3. Carbonic acid - Wikipedia

    en.wikipedia.org/wiki/Carbonic_acid

    The molecule rapidly converts to water and carbon dioxide in the presence of water. However, in the absence of water, it is quite stable at room temperature. [5] [6] The interconversion of carbon dioxide and carbonic acid is related to the breathing cycle of animals and the acidification of natural waters. [4]

  4. Carbon dioxide cleaning - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide_cleaning

    Equipment costs for a carbon dioxide snow cleaning system can range from US$1500 for a basic system to $50,000 for a high-end automated unit. [ 4 ] : 292 Material costs are comparatively low, although ultra-pure CO 2 must often be used to avoid the introduction of new contaminants.

  5. Alkali metal - Wikipedia

    en.wikipedia.org/wiki/Alkali_metal

    The formation of an alkali metal nitride would consume the ionisation energy of the alkali metal (forming M + ions), the energy required to break the triple bond in N 2 and the formation of N 3− ions, and all the energy released from the formation of an alkali metal nitride is from the lattice energy of the alkali metal nitride.

  6. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  7. Alkaline earth metal - Wikipedia

    en.wikipedia.org/wiki/Alkaline_earth_metal

    Alkaline earth metals reduce the nonmetal from its oxide. 2Mg + SiO 2 → 2MgO + Si 2Mg + CO 2 → 2MgO + C (in solid carbon dioxide) Reaction with acids. Mg + 2HCl → MgCl 2 + H 2 Be + 2HCl → BeCl 2 + H 2. Reaction with bases. Be exhibits amphoteric properties. It dissolves in concentrated sodium hydroxide. Be + NaOH + 2H 2 O → Na[Be(OH ...

  8. Lime (material) - Wikipedia

    en.wikipedia.org/wiki/Lime_(material)

    Pure lime is soluble in water containing carbonic acid, a natural, weak acid which is a solution of carbon dioxide in water and acid rain so it will slowly wash away, but this characteristic also produces autogenous or self-healing process where the dissolved lime can flow into cracks in the material and be redeposited, automatically repairing ...

  9. Carbon dioxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_dioxide

    Carbon dioxide is the lasing medium in a carbon-dioxide laser, which is one of the earliest type of lasers. Carbon dioxide can be used as a means of controlling the pH of swimming pools, [139] by continuously adding gas to the water, thus keeping the pH from rising. Among the advantages of this is the avoidance of handling (more hazardous) acids.
